yeah - it's small, inexpensive, has 3 functions - if you have stackcables or enough mults, you can patch it to get 7 different, but related modulation outputs from a single modulation source
it's similar with matrix mixers - put mult x modulation sources in get x more related modulation outputs
once you've got a few modulation sources - things like these and cascading vcas, switches etc are generally less expensive for getting more out of them than getting more modulation sources and will lead to more interesting modulation -that's not to say never get any more modulation sources - it's more: there are other ways, as there almost always are in modular

Utility modules are the dull polish that makes the shiny modules actually shine!!!
sound sources < sound modifiers < modulation sources < utilities
